The Norwesco 200 Gallon Pest Control Operator (PCO) Tank is a White polyethylene tank built for the spray-rig and applicator trade, holding 200 gallons in a compact 37" x 37" x 48" envelope. It carries a 1.5 specific-gravity rating, which is what sets a true PCO tank apart from a plain water tank: the resin is rated to carry contents up to 1.5 times the weight of water, so the tank handles dense product without distorting or fatiguing the walls over a season of use. If you have searched for a Norwesco 200 gallon tank or a PCO tank and want one that is honest about what it can hold, this is the right spec.
Will it work for your rig?
The footprint is 37.0" x 48.0", and the tank stands 37" tall, so it drops into most utility-bed and trailer-mount layouts without crowding the rest of your equipment. Filled with water, the contents weigh about 1,668 lb; because the shell is rated to 1.5 specific gravity, it is engineered to carry up to 2,502 lb of contents at full rated density. Those two numbers matter when you size your trailer axles, tongue weight, and pump mount, so plan your platform around the heavier figure if you will run product denser than water. If you are choosing between this and another size, the Tank Sizing Calculator and Tank Sizing Guide will help you match capacity to your gross vehicle weight.
Fittings and outlet — confirm from the drawing
Fitting and outlet configuration is shown on the technical drawing on this page rather than published here, so confirm the outlet size, bulkhead thread, and vent before you order mounting hardware or plumbing. Build your mount and platform around the rated contents weight, and brace the full base on a flat surface instead of hanging the tank off a partial frame — at 2,502 lb of rated load, that support is not optional.
The mistake to avoid
The 1.5 specific-gravity rating is a ceiling, not a free pass. Before you fill it, confirm the actual specific gravity of your product and verify chemical compatibility for the exact concentration you intend to carry against the manufacturer's chemical-resistance chart. A tank rated to 1.5 SG still has to be compatible with the chemistry going into it, and that is a separate question from weight. Match the elastomer too: the outlet fitting, bulkhead gasket, and any valve must be rated for your product and concentration, not just the polyethylene wall — a tank rated to 1.5 SG can still leak at an incompatible gasket. The other common miss is mounting, which is why bracing the full base matters as much as the wall rating.
